IMPROVEMENT IN COMBINEDRA'ILWAY AND CONDUIT.

Specification forming partvof Letters Patent o. 198,060, dated December 11, 1877; application filed september 17, i877.

the following to be a full, clear, and exact de-A scription thereof, reference being had to the accompanying drawings My invention consists of a novel arrangement of water-pipes, conveying water for irrigation and other uses, in combination with a permanent way for transportation purposes.

My invention will bel more fully described to the accompanying drawings, in which- Figure 1 is a perspective view. Fig. 2 is a longitudinal section through pipe.

L et A represent a road-bed which is graded, and the ties or sleepers laid inthe ordinary manner for receiving the rails. Upon the ties B pipes C D are laid, and on these pipes rails are secured, as shown, These rails are curved to t the top of the tube, and are secured in place by chairs iitted for the. purpose. These chairs have a stem, I, extending into the pipe, with countersunk heads, so that one of the chairs or fastenings may be turned to release or secure the rail.

- The ties B are prepared for receiving the pipes by a concave groove, G, out in their face at either end, in which the pip-es are laid and secured by any suitable mechanical device. The distance between the rows of pipe from center to center will conform with the gage of the road. The rails L are secured to the pipes in chairs H, which bind them firmly and securely together.

The pipes C D consist of an inner tube and an outer tube or binding-rings. The inner tube is formed of beveled staves or lengths J, of any suitable material, so placed that the f continually break joints at the meetingl ends, the meeting `ends of the different lengths form! ing a spiral on the periphery of the tube, as shown in section, Fig. 2.

The inner pipe, formed of beveled staves J, is inclosed by an outer tube or rings, K, of iron or other suitable material. This arrangement of pipe is easily made, the inner tube,

composed of beveled staves, being formed inside the Outer tube or rings, 'which can be added as fast as the inner tube is formed, and it forms a strong and in every way desirable pipe for conveying water, being of equal strength at every point, and having no large joints to open, causing a waste of water and destruction of earth-work. It alsov forms a continuous and elastic support for the rails, and there are no joints to be opened or to act as ai point 'where an abrupt curvature can be ma( e.

adapted for the construction of pontons, the material forming it being of suitable and compact shape for easy transportation in country of any topography.

Double lengths of pipe can be formed and secured to ties on upper side, as shown,beside a rivers bank, and then one end of the train or continuous pipe allowed to float across, thus forming easily and quickly a superior pontonbridge of great capacity when it is made water-tight.

, The combination of pipe and track on the same road-bed is of great advantage in many ways. The pipes, as a support for` the rail, are continuous and elastic, greatly reducing the danger of accidenty from broken rails,.and forming a smooth and easy-running road,I enabling me to make straight lines between points which could not be aii'orded without the combination. y

The, water-pipe, by being laid on a graded road-bed, loses less of head and of force than by the usual method of laying pipes, is not subjected to the severe pressure exerted upon pipes which follow the vertical contour of the land, and any break that may occur is easily found and quickly reached for repairs.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

v1. The pipes C D, composed of the beveled staves or longitudinal strips J, so placed that their meeting ends form a continuous spiral, in combination with the outer binding tube or rings K, substantially as and for the purpose described.
